12. St. Louis Rams (previously 12th)

Biggest thing we learned this week: Jared Cook, who was never really used properly in Tennessee, is going to have a huge year with Sam Bradford throwing to him.

11. Baltimore Ravens (previously 5th)

Record: 0-1

Week One result: 49-27 loss to Denver

Biggest thing we learned this week: Joe Flacco has no one to throw to without Dennis Pitta and Anquan Boldin.

10. Washington Redskins (previously 6th)

Record: 0-1

Week One result: 33-27 loss to Philadelphia

Biggest thing we learned this week: It might take RG3 a couple of weeks to get back to his old self. He wasn't stepping into his throws in the first half.

9. Atlanta Falcons (previously 9th)

Record: 0-1

Week One result: 23-17 loss to New Orleans

Biggest thing we learned this week: Steven Jackson is a massive improvement over Michael Turner at running back.

8. New Orleans Saints (previously 18th)

Record: 1-0

Week One result: 23-17 win over Atlanta

Biggest thing we learned this week: The defence looked much improved under new coach Rob Ryan. If they can even be mediocre on that side of the ball they'll contend.

7. Green Bay Packers (previously 7th)

Record: 0-1

Week One result: 34-28 loss to San Francisco

Biggest thing we learned this week: This was the worst possible opponent to face in Week One. We won't know if the defence is improved for a few more weeks.

6. Chicago Bears (previously 10th)

Record: 1-0

Week One result: 24-21 win over Cincinnati

Biggest thing we learned this week: Jay Cutler has been hit more than any QB in the league in recent years, but Chicago only let up one sack on Sunday.

5. New England Patriots (previously 8th)

Record: 1-0

Week One result: 23-21 win over Buffalo

Biggest thing we learned this week: Tom Brady is going to throw a ton of five-yard passes this year without Rob Gronkowski and Aaron Hernandez.

4. Seattle Seahawks (previously 3rd)

Record: 1-0

Week One result: 12-7 win over Carolina

Biggest thing we learned this week: The offensive line was shaky. They only averaged 2.7 yards per carry and Russell Wilson was under duress all day.

3. Houston Texans (previously 1st)

Record: 1-0

Week One result: 31-28 win over San Diego

Biggest thing we learned this week: The Texans out-gained San Diego by 200 yards, ran 50% more plays, only turned it over once, and threw just 11 incomplete passes, but only won by three. This game was too deeply weird to isolate any one takeaway.
